HIERARCHICAL MEMORY MAGNETORESISTIVE RANDOM-ACCESS MEMORY (MRAM) ARCHITECTURE

摘要

A hierarchical memory magnetoresistive random-access memory architecture is disclosed. In a particular embodiment, an apparatus includes a first magnetoresistive random-access memory (MRAM) device corresponding to a first level in a hierarchical memory system. The apparatus includes a second MRAM device corresponding to a second level in the hierarchical memory system. The first MRAM device has a first access latency and includes a first magnetic tunnel junction (MTJ) device having a first physical configuration. The second MRAM device has a second access latency and includes a second MTJ device having a second physical configuration. The first access latency is less than the second access latency.
